Here are two poems for April Fool's Day, which pull off some difficult rhymes. The practical joke on you is that they're limericks, but they aren't very funny.
A clever young man from Australia
Wrote a limerick that was no failure,
Though in the last line
He didn't decline
Abstruse verbal paraphernalia.
The subject, a small juicy orange,
Inspired a limerick most strange.
Though the meter was great,
It could not compensate
For half-rhymes that made the reader cringe.
